The lack of intrinsic active sites for photocatalytic CO
Quasi-2D perovskites have recently flourished in the field of luminescence due to quantum-confinement effect and efficient energy transfer between different n phases resulting exceptional optical properties. However, owing lower conductivity poor charge injection, quasi-2D perovskite light-emitting diodes (PeLEDs) typically suffer from low brightness high-efficiency roll-off at high current densities compared 3D perovskite-based PeLEDs, which is undoubtedly one most critical issues this...
Tin (Sn)-based perovskites are being investigated in many optoelectronic applications given their similar valence electron configuration to that of lead-based and the potential environmental hazards perovskites. However, formation high-quality Sn-based perovskite films faces several challenges, mainly due easy oxidation Sn
Exciton-polariton dynamics in 2D materials have garnered substantial attention across diverse scientific domains for fundamental research with potential applications optoelectronics. However, practical implementation has been hindered by the challenge of maintaining stable and long-range polariton propagation. Here, we present an innovative material platform featuring extensive monolayer WS2/Al2O3 superlattices (a square a length >0.5 cm) coupled to waveguide mode designed host...
Pulmonary edema, i.e. excess of extravascular fluid in lungs, is a common manifestation various clinical conditions. Although the etiology pulmonary edema deduced with help history, physical examination and biochemical radiological investigations, computer aided evaluation will be helpful for physicians determining course management condition. In this study we present texture analysis chest x-ray, using Gabor filter one machine learning techniques, Support Vector Machine (SVM), to...
A large conductivity difference exists between the {0001} and {101̄0} faces of a GaN wafer. Current-rectifying I – V curves were obtained with electrodes contacting both simultaneously.
The utility of intracystic administration indocyanine green for near-infrared fluorescent cholangiography in acute calculous cholecystitis initially treated with percutaneous transhepatic gallbladder drainage (PTGBD) was described this report. Two cases who underwent guided interval laparoscopic cholecystectomy two weeks post-PTGBD were studied retrospectively. Both patients diagnosed moderate based on diagnostic criteria the Tokyo guidelines. routes utilized during surgery, first through...
Abstract Owing to their excellent carrier mobility, high absorption coefficient, exceptional quantum efficiency, and low‐cost solution processability, perovskite dots (PQDs) are a promising candidate for photodetection. However, PQDs‐based photodetectors typically show poor optoelectronic performances, mainly limited by weak light–matter interaction. In this work, MAPbBr 3 PQDs hybridized with graphene (Gr) morphologically controlled plasmonic gold nanocrystals (AuNCs) demonstrate superior...
Hot electrons (HEs) represent out-of-equilibrium carriers that are capable of facilitating reactions which inaccessible under conventional conditions. Despite the similarity HE process to catalysis, optimization strategies such as orbital alignment and adsorption kinetics have not received significant attention in enhancing HE-driven reaction yield. Here, we investigate catalytic effects using a compositional catalyst modification (CCM) approach. Through top-down alloying systematic...
The current study describes a technique for reconstructing three dimensional surface from multiple images of the (single camera) endoscopic video. A 3D shape scene in each image frame video was reconstructed using shading technique. characteristic feature points on 2D were detected SURF algorithm and features matched BRIEF Hamming distance criteria. between consecutive frames used to find transformation matrix align surfaces frames. Using matrix, stitched (registered) together. method...
Laparoscopic surgery is indispensable from the current surgical procedures. Conventional laparoscope (endoscope) systems produce 2D colored video images which do not provide surgeons an actual depth perception of scene. In this work, problem was formulated as synthesizing a stereo image monocular (conventional) by incorporating into them information 3D CT model. The method applied to at rate up 5 frames per second visualize its video. Correlation coefficients between maps calculated with our...
Introduction: Endoscopic surgery causes reduced injury to tissues which helps in rapid recovery and less painful post-operative period of patients. However, its narrow field view loss depth perception endoscope image make surgeon's task difficult. Moreover, endoscopic surgeons can only see the surface surgical anatomy. In this study these limitations have been addressed with development an augmented reality system 3D visualization. Method: The is comprising infrared based optical tracker, 2D...
Sub-surface information during a laparoscopic surgery is captured with near infrared imaging where the tissue highlighted help of an indocyanine dye injected to patient before surgery. The surgeons can use such system surgery, however, they need swap light source between infra-red and white complete Swapping causes inconvenience increase in time current study aims develop method for superimposing tracking imagery on video acquired under light. In this study, was registered one from endoscope...
Owing to its atomically thin thickness, layer-dependent tunable band gap, flexibility, and CMOS compatibility, MoS$_2$ is a promising candidate for photodetection. However, mono-layer MoS2-based photodetectors typically show poor optoelectronic performances, mainly limited by their low optical absorption.

In USG-guided interventional procedures, the surgeons need to mentally register reference data set (computed tomography [CT] or magnetic resonance [MR] images), and working of USG (real-time). This study presents a system combine real time information with preoperative 3D CT virtual model using landmark registration. The future goal this is apply for radiofrequency needle tracking during surgery.
Decreasing the number of interfacial defect states and enhancing charge transfer ability transport layers have become promising strategies for increasing efficiency stability perovskite solar cells (PSCs). In this study, we used a holistic interface strategy, employing three-dimensional (3D) triphenylamine-based nanographene (NG) precursors with well-defined molecular structures presenting various functional units (F, Br, OMe), to achieve efficient inverted PSCs. The 3D NG precursor formed...
